provement in Denatured Alcohol, of which the following is uspecification. h

In accordance Wlih Hie present invention a denatured alcohol is preparedcontaining as a denatui'nnt a dilute-arid insoluble product formedduring'the treatment-of qolefine-containing hydrocm'briu gases withsulfuric acid of a sulfuting strength. When such gases, for example, thegases resulting from the cracking or pressure distilliltion ofhydrocarbon oils, are caused to Contact at a controlled ten'ipcrature,preferably below 30 1, with sulfuric arid of a sul'fatins strength, i.e., corresponding to a density above 1.7:? and below 1.8%, prefera-hi3about 1.8, on acid extruci' is formed which contains the mid sulfates ofthe o3efines of the gases higher ihun ethylene with a product which, ondilution. separates out as an oily layer. This product is wmplex mixturecontaining polymer .wl iuisn fiurnfei'l hydrorm'bons, suifur rompi anctr, dark brown to block in rolor I y of 0.85 to 0.90, and is readilymiscible 'Jiih strong alcohol and kerosene. It begins to boil at about(BTU. and its boiling point risesgradunlly as evaporation ronfinues tothe formation of :L pin-by or coke-like product. When added to alcoholit cannot be completely separated therefrom by from tional distillation.

If dosired, the product may be subjected to distillation, anda-distillato having a suitable range of iioilingpoints, soy 63 to 256 C.employed as n denutumnt. This dis- Application filed Hiarch 5, 1921.Serial No. 449,896.

(illate has a brownish color, a sulfurous odor, and a density of about0.84 to 0.85 and an analysis shows from 10 to 15% of sulfur.

Either the imdistilled or distilled product may be added to alcohol inany desired proportion, and may. if desired, be previously admixed withkerosene or benzo]. For example, one part of the product may be admixedwith ,three parts of kerosene, and used as a dennturnntjin theproportion of 2 to 3' :illons of the mixture to 100 gallons of'et iylalcohol (190 proof), 1 claim:
